HYDRANT.

Specification of LetterslPatent No. 32,338, dated May 14, 1861.

To all whom 'it may concern:

Be it known that I, JOSEPHNEUMANN, of the city of Philadelphia, in the State of Pennsylvania, have invented a new and useful Improvement in Hydrants; `and I do h'ereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, shows a central, longitudinal, section of the improvement applied; and Fig. 2, a plan view of the same without the key rod and the upper section of the cap.; like letters, when in both figures, indicating the same parts.

My invention has for its object the prevention of earth or sand from coming in contact with the upper joint of the hydrantcock, and thus, in a more simple and effectual manner, preventing the usual rapid grinding away, and consequent early leaking, of the said joint.

It consists of a short, tubular, case or guard attached immediately to and around the upper part of the barrel of the cock, and `within the usual external hydrant case, substantially as hereinafter described.

In the drawings, A, represents a common hydrant-cock, B, the case or guard; and O. the usual key-rod for operating the plug of the said cock. The case (B), in 'this instance, is made in two parts, b', b, each being a section of metal pipe of suitable diameter. The section b', is fitted and soldered closely around the projecting upper part 0f the barrel a', of the cock (A), and so as to project about three quarters of an inch, more or less, above the said barrelthe inner side of the Vsaid projecting part' being provided with screw threads, CZ, substantially as seen in Fig. 1. The Lipper section, b, of the cap (B), consists of a section of pipe of suflicie-nt length to reach from the cock (A) to a short distance above the surface of theground in which the hydrant may be placed. Its lower end has screw-threads, cut in its Outer side, which match those on the inner side of the section b". `The upper end of this tube, b, has a disk, e, soldered` fast within it, and through a hole f, in its center, the key'rod (C) is movable. Packing may be fixed in the said hole (f), for the purpose of keeping out dust; or, a disk of leather lorvulcanized gum, g, may be fixed to the rod (C), as seen in Fig. l, for the same purpose; After the rod (C) has been inserted up through the cap (6), and pinned fast to the plug (a) in the usual manner, the said section (b,) of the case (B) is screwed, water tight, into the section b', and the disk (g) then slipped down so that it shall coverl the hole )cc-the said section (6) extending up, through the usual external case of the hydrant, above the surface of the ground.

In all out-door hydrants subject to freezing weather, a waste hole is provided in the lower part of the cock, generally, for relieving the vertical outlet pipe of water when the hydrant is shut; but, in most grounds, especially in those where the hydrant is frequently used, the waste water often backs up and submerges the cock, and being generally mixed with earth and sand, washed up from thel ground below, the upper joint of the cock soon becomes worn away thereby so as to allow leaking; but it will be evident that the present invention will effectually prevent this access of dirt, sand, and water. because the upper'joint of the cock is -perfectly inclosed, in a watertight manner, within the case or guard (B) while at the same time the waste-water is permittedto freely discharge itself from the said cock. It is simple and inexpensive of construction, easily applied, and does not access to the cock in repair- JOSEPH NEUMANN.
